Detailed Description

template<class T>
class PixelBufT< T >

Description:

These templated classes allow you to set up a buffer for pixels that will automatically deallocate the buffer when they goes out of scope. All methods of this class are implemented by the system.

Note the following typedefs set up for the standard pixel storage formats.

typedef PixelBufT<UBYTE> PixelBuf8;

typedef PixelBufT<USHORT> PixelBuf16;

typedef PixelBufT<BMM_Color_24> PixelBuf24;

typedef PixelBufT<BMM_Color_32> PixelBuf32;

typedef PixelBufT<BMM_Color_48> PixelBuf48;

typedef PixelBufT<BMM_Color_64> PixelBuf64;
